Over the ring 7', the shackle plates :0 and the hooks 72 and. also over-the hook illustrated in Figures 3 and 4, a thin, annular protecting sheet a (Figure 1) is riveted, so that all the parts are protected froin'fdust and water. a I

When detaching and connecting the rim parts a and b, therefore, no operation is necessary other than the rotating of the pin a through about=180' degrees. This operation does not have to overcome any apprecivso able ij'esistance, because there is no friction worth mentioning, and mud does not hinder the steel ring frominoving out of the hooks It.
